.IM/ENTOR. PETE@ BGHE 777 ATTORNEYs Patented Feb. 9, 1932 UNITED STATES PETER BEGHET'II, F SAN FRANCISCO, CALIFDRNIA WIRE TWISTER Application led. November 11, 1929. SeraI No. 406,380.

T his invention relates to wire twisters as used in, 'the erecting; of concrete forms in building' ott concrete structures general-ly, and has :tor its objects a simple and eileotive de o vice for the piu-pose mentioned, particularly adapted to work in corners and places where prior tools oit this hind patented by ine could not be eilieilfitly used.

ln the drawings Fie. l is a perspective view l oit one torni ot iny twister', Fig. 2 is an enlargred brolen side view thereof with portions ot the jaws, linl and handle broken awayn and l is a perspective view of a ined ilied loi-1n ot my improved twister.

l ln lnitbcr detail the twister comprises a pair oit handles l-2, the latter pivoted at 3 between a pair et lugs 4 projecting upward :troni handle i, and handle l provided with an ei'itwardly a nd forwardly projecting horn 5 having at its outer end a traiisversely eX- tendingr heel or foot o with a substantially flat enter surface.

llt the opposite end of handle l is a vice handle l slidzible through a ring 8, and a link E) piro-ted in a loop l() welded to the underside oit handle l in a manner to swing over the top et handle to engage in any of several notches ll formed on the end et handle 2 which is curved downwardly toward handle l as best shown in Fig. 2.

.Jin-st back ot' lons is a pair et interlocking jaws 'l2 and 13 carried respectively by handies l and i2, jaw l2 taking the torni of a chan-- nel open on top and with front, baelr and end U walls` the Channel extending* transversely of the handles while jaw 123 is ot simple rectangg'nlar shape Fitting lreely within the channel so te clamp a pair ot wires 114 therein, one to either side ot lngis Ll, and put a quadruple lrinlr in each wire when the handles are brought together, and in 'which position the handles are locked by swinging the linlr 9 into engagement mer handle 2, all as clearly shown in Fins. l and The construction shown in Fig. 3 saine in all respects w bored, except that the inlr 9 is dispensed with` and either one or both handles is notched or inidolated as shown 'l'or handle 2 la tig. 8 and a heel; link 'l5 is loosely and is the i similarly nurnslidably mounted on handle l so as to hook over handle 2 at any point therealong to clamp the handles together, the undulations in the handle preventing.;v the hook link from becoming displaced.

ln use, the hand levers are opened, the two wires to be twisted are laid across the jaws and clamped, then with the heel (5 resting against the form structure the wires are pulled taut, and twisted by revolving the tool with the 'vise handle.

lt will be noted that the handles lie comparatively close together, and as the vise handle can be slid baci; and forth, and the operator does not have to hold en to `the handles to prevent the wires slipping, it is possible to work quickly in places where other twisting tools ot this character could not be used to advantage.

l claim:

l, A wire twister comprising a pair oiE hand levers pivoted atthe forward end to open rearwardly at an angle and to close substan tially parallel, an outwardly and forwardly projecting foot on one of the levers, a pair of transversely extending` jaws on said handles haelt of the pivotal point 'formed to lit one within the other and means en one ot said jaws to prevent a wire clamped therein from coming out at the end of the jaws.

2. A wire twister comprising` a pair of hand levers pivoted at the forward end to open rearwardly at an ang-le and to close substantially parallel, an outwardly and forwardly projecting toot on one oi' the levers, and a pair of transversely extending jaws on said handles back of the pivotal point formed to t one within the other in a manner to kink a wire in several places when clamped between the jaws the pivot of the hand levers being positioned above the jaws.

3. A wire twister coinprisin a pair of hand levers pivoted at the forward end 'to open rearwardly at an angle and to close substantially parallel, an outwardly and 'forwardly projecting toot on one oi the levers, and a pair oit transversely extendingl jaws on said handles hach of the pivotal point formed to lit one. within the other, one olf said jaws being` channel shaped, and the other jaw extending 100 j hand levers pivoted longitudinally within said channel whenthe jaws are closed.

4. A wire twister comprising a pair of hand levers pivoted at the forward end to open rearwardly at an angle and to close substantially parallel, an outwardly and forwardly projecting foot on one of the levers, andy a pair of transversely extending jaws on,V said handles back of the pivotal point formed t0 fit one within the other, one of said jaws being channel shaped and closed on its end, and the other jaw extending longitudinally within said channel when the jaws are closed.

5. A wire twister comprising aV pair of Y hand levers pivoted togetherradjacent their `forward ends, an outwardly audnforwardly extending foot on one of said levers, and a pair of jaws, one on each lever adjacent the pivotal point extending transversely of the levers arranged in oifset relation to one another and provided with a plurality of edges whereby to put four kinks in a wire gripped therebetween.

6. A wire twister comprising a pair of together adjacent their forward ends, an outwardly and forwardly extending foot on', one of said levers, and a pair ofjaws, one on each leveradjacent the pivotal point `extending transversely of the levers arranged in offset relation to one another whereby to put a kink in a wire gripped therebetween, and a vise handle slidably mounted in a ring formed on the end of one of the levers.

7 A wire ltwister comprising a pair of handy levers pivoted together adjacent their forward ends, an outwardly and forwardly extending foot onone of said levers, Vand a pair of jaws, one-on each lever adjacent the pivotal point extending transversely of the leve-rs arranged in offset relation to one another whereby to put a kink in a wireV gripped therebetween, a vise handle slidably mounted in a ring formed on the end of one of the levers, and means for locking the handles together.
